This Standard specifies the mechanical properties of nuts with specified proof load values (coarse thread) when tested at room temperature.<\/p>\n
\nProperties will vary at higher and lower temperature.<\/p>\n
\nIt applies to nuts<\/p>\n
\n– with nominal thread diameters d up to and including 39 mm;<\/p>\n
\n– with diameter\/pitch combinations according to JIS B 0205-2 (coarse thread);<\/p>\n
\n– with thread tolerances 6H according to JIS B 0209-1 and JIS B 0209-2;<\/p>\n
\n– with specific mechanical requirements;<\/p>\n
\n– with widths across flats as specified in JIS B 1002 (shaded values are excluded);<\/p>\n
\n– with nominal heights greater than or equal to 0.5d;<\/p>\n
\n– made of carbon steel or low alloy steel (see NOTE 1)<\/p>\n
\nIt does not apply to nuts requiring special properties such as<\/p>\n
\n– locking abilities (see JIS B 1056);<\/p>\n
\n– weldability;<\/p>\n
\n– corrosion resistance (see JIS B 1054-2);<\/p>\n
\n– ability to withstand temperatures above +300 "C or below -50 "C (see NOTE 1).<\/p>\n
\nNOTE 1 Nuts made from free-cutting steel should not be used above +250 "C.<\/p>\n
\nNOTE 2 For special products such as nuts for high-strength structural bolting, and overtapped nuts for use with hot-dipped galvanized bolts, see the product standards for appropriate values.<\/p>\n
\nNOTE 3 For assemblies with threads having tolerances wider than 6H\/6g, there is an increased risk of stripping; see also table 1.<\/p>\n
\nNOTE 4 In the case of thread tolerances other or larger than 6H, a decrease of the stripping strength should be considered (see table 1).<\/p>\n
